Project PEP

AS Jimmy Choo's Tamara Mellon prepares to watch her debut high street collaboration hit H&M stores next month she is also busy working on another collection. Jimmy Choo's Project PEP collection launches at Selfridges tomorrow night - in partnership with the Elton John Aids Foundation - and there are already 1,000 names on the waiting list for the pieces.

PEP stands for "post-exposure prophylaxis", drugs which - if given to those exposed to the HIV virus within 72 hours of exposure - reduce the chances of developing the virus by 79 per cent. A quarter of the net sales from the collection will fund Project PEP at the Simelela Centre in Cape Town, with a view to rolling out the system across South Africa.

"I think there is a responsibility for any company when it gets to a certain size to start giving back," Mellon said of her involvement in the project. "Going to Africa and meeting the women makes you understand how brave they are. It puts everything into perspective."

"One of the things I'm most proud of about the Aids Foundation is that we don't just ask people for money," Elton John told The Telegraph. "We try to build partnerships with people and companies that share our passion for this fight."
